CONTAINER.

Specification of Letters Patent.

Patented Aug. '7, 1917.

Application filed November 28, 1914.. Serial No. 874,379.

specification, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to containers and more particularly to closures therefor.

The invention seeks to provide a closure durable in structure, neat in appearance and convenient and reliable in operation.

In the accompanying drawings forming part of this specification, and in which like reference numerals designate corresponding parts, the invention is shown as applied to a container adapted to hold tooth powder, talcum powder, or other similar powdered or comminuted material.

Figure 1 is a side elevation of a container embodying the invention.

Fig. 2 is a plan view of the top thereof showing in dotted lines parts of the closure in open position which are secured on the under side of the top.

Fig. 3 is a plan view of the under side of the top showing the closure in closed position.

Fig. 4: is a central sectional elevation showing the closure in closed position and taken on the line t-t of Fig. 1.

Fig. 5 is a plan view of the top with the turn key and outer plate removed.

Referring now more particularly to the various parts as illustrated in the drawings, 1 is the body of the container, cylindrical in form, and having a circular, permanently fixed top 2 to which the closure is applied.

The top 2 is provided with an outlet opening 3 through which the contents of the container may be ejected. On the under s1de of the top is fixed a rotatable valve member l designed to open and close the opening 3.

The valve member is held in place by studs 5 and 6 secured thereto and passing through spaced slots 7 and 8 formed in the top 2. These studs are preferably formed integral with a turn key 9 by means of which the valve member is rotated. The movement of the valve member is preferably limited by so arranging the length and position of the slots, or one of them, as to contact wlth one or both of the studs 5 and 6 when the valve member has reached the desired limits of its movement, the movement of the valve member being stopped in one direction when the opening 3 has been closed and being stopped 1n the opposite direction when the opening 3 has been entirely uncovered.

10 is an outer plate through which the studs 5 and 6 pass and by means of which the plate is secured to the turn key 9 and to the valve member 4. The studs preferably act to clamp the outer plate 10 and the valve member 4 in close frictional engagement with the intervening top 2 so that there may be no danger of the valve member moving from one position to another through accident or an unintentional jar to the container.

In the preferred arrangement, the outer plate is circular in form and rotatably fits in a countersunk recess 11 formed in the top 2. The recess thus serves to center the outer plate 10 and the valve member 4 and contributes to the strength and ruggedness of the structure. It is important that the slots 7 and 8 shall be permanently covered so that the contents of the container may not sift through them. Forthis purposeboth the valve member 1 and outer plate 10 are of sufficient extent to overlap and permanently cover these slots, although it is obvious that either the plate 10 or valve member 4 might be relied upon to cover the slots.

For a reliable closing of the opening 3, it is advantageous that the valve member press with a certain resiliency against the under surface of the top so as to spring into the opening 3 when closing the same. Where the closure is applied to a small container, such as a tooth powder can, the elements of the closure are necessarily small and the desired resiliency in the valve member must be provided by giving to the valve member a special form adapted to the purpose. The valve member 1 is, therefore, provided with an elongated valve finger 12 formed with a hump 13 so as to press against the under surface of the top 2 with the desired resiliency. In its preferred form, as shown in the drawings, the valve member 4 is formed of sheet metal in which are cut slots 14 and 15 which extend from one edge of the valve member to near the opposite edge thereof, the valve finger comprising the metal strip between these slots and extending beyond the edge of the plate. In this way suificient length for the valve finger is provided to secure the required resiliency. It will be noted that the studs 5 and 6, passing through the spaced slots 7 and 8. into. engagement with the valve member 4, contribute largely to the strength and ruggedness of the structure. It will also be noted that the turn key 9 rotates on its vertical axis and that the use of a central pivot pin connecting the valve member with the top 2 is obviated. Pivot pins when used in structures for the same general purpose are unsatisfactory and are generally a source of Weakness. In most cases they work loose and are easily broken.

l/Vhile the invention is shown in What is believed to be its best form, it is obvious that various, changes in the construction may be made without departing from the spirit of the invention.

What I claim is:

1: A container having an opening and two spaced slots in its wall, a rotatable valve member located on the inner side of said wall and having an elongated resilient valve finger arranged to close and open said opening, and a turn key arranged to rotate on its axis and having studs passing through said slots and secured to said valve member.

2. A container having an opening and two spaced slots in its wall, a rotatable valve member located on the inner side of said Wall and arranged to close and open said opening, and a turn key having studs passing through said slots and secured to said valve member, said wall having a circular.

recess on its outer side, an outer plate secured to the turn key and fitting rotatably in said recess to firmly center the turn key and valve member.

3 A containerhaving an opening and two spaced slots inits wall, a rotatable valve member located on the inner side 01"? said wall and having an elongated resilient valve finger arranged to close and open said opening, and a turn key having studs passing through said slots and secured to said valve member, said Wall having a circular recess on its outer side, an outer plate secured to the turn key and fitting rotatably in said recess to firmly center the turn key and valve member.

4. A container having an opening and two spaced slots in its wall, a rotatable valve member located on the inner side of said wall and arranged to close and opensaid opening, and an outer imperiorate, rotatable plate covering said slots and rigidly secured to said valve member by studs passing through said slots and clamping the outer plate and valve member in close contact with the wall of the receptacle, said opening being beyond the margin of said outer rotatable plate.

5. A container having an opening and two spaced slots in it's wall, a rotatable valve member located on the inner side of said wall and arranged to close and open said opening, and an outer imperforate, rotatable plate covering said slots and rigidly secured to said valve member by studs passing through said slots and clamping the outer plate and valve memberin close contact with the wall of the receptacle, the wall of the receptacle having a circular recess in which the outer plate rotatably fits, said opening being beyond the margin of said outer rotatable plate.

6. A container having a circular recess in its wall, an opening beyond said recess and two slots located in said recess on opposite sidesthereof, a rotatable valve member located on the inner side of said wall over said slots, said valve member having an elongated resilient valve finger adapted to: close and open said opening, an outer rotatable plate fitting in said recess, and a turn key having studs passing through the outer plate and slots into engagement with the valve member. 1

7 A container having an opening and two spacedslots in its wall, a movable valve finger located on the inner side of said wall and arranged to closeand open said opening, a turn. key arranged to rotate on its axis and having studs passing through said slots and secured to said valve finger, and a permanent covering for said slots secured to and moving with said turn key.
